Specification of Letters Patent.

Patented Jilly a, rare.

Application filed December 18, 1911. Serial No. 666,517.

citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Rotary Motors, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to rotary motors and more particularly to motors of this type adapted to drive boiler tube cleaners, although it may. be used for other purposes.

The objectof my invention is to provide an improved motor simple, strong and durable that can be easily assembled and readily taken apart.

A further object of my invention is to i provide improved means adapted to relieve the friction between the stationary and rotary members and to balance the rotary member.

A further object is to provide-improved means for lubrication and for the admission and discharge of the motive agent.

WVith these and other objects in view my invention consists of the constructions and combinations hereinafter described and set forth in the claims.

- In' the accompanying drawings which form a part of this specification Figure 1 is a longitudinal section of a motor embodyv respectively of Fig. 1. Fig. 5 shows detail of spring pressed dowel-pin,. Fig. 6 is a longitudinal section showing modifications and Figs. 7, 8 and 9 are cross-sections on the lines 7-7-, 8 8 and 99 respectively of Fig. 6, and Fig. 10 shows another modification.

Like numerals represent the same parts in the several views.

In the drawings 1 represents a motor cylinder having an outwardly projecting ring 2 forming an abutment. A two-part casing 3 having heads at its outer ends preferably formed integrally therewith extends over and is screw-threaded to said cylinder with its inner ends tightened against said abutment.

In the present instance I have shown the motor cylinder forming a chamber of such dimensions that when the rotary member 4 is mounted therein it will contact with the walls of the chamber in two places, opposite each other, forming two oppositely disposed chambers 5 and 6 as particularly shown in Fig. 3. Piston blades 7 are seated in recesses 8 of, the rotary member and are adapted to moveradially into the chambers 5 and 6 in a well known manner.

The rotary member I preferably form with front and rear journals integral therewith of less diameter than the body thereof as shown. A motor journal bearing member 9 is seated in one part of the casing 3 and a removablebushing 10 is preferably provided to carry the rear journal of the rotary motor member; and a removable bushing 11 seated in an opening in the head of the other part. of said casing is'provided to carry the front journal of said rotary motor member. Said front journal portion projects through said head and is-screwthreaded at 12 to attach a tube cleaner or openings in the rear of the piston blades as shown. It will be seen these ports are so arranged that the transverse portions can be made by boring through the periphery of the rotary motor and its rear journal and the longitudinal section of it can be bored,

from the outer end of the rear journal and a plug 14 employed to close the open end. The bushing 10 is provided with inlet ports 15 adapted to register with the ,ports 13 of the rotary motor member. Said bushing is secured to the motor bearing member 9 by a key 16 and said bearing member is secured to the cylinder 1 by a dowel-pin 17 s0 that the ports 13 and 15 will be held in proper relation to admit the motive agent. The longitudinal section of the'port 15 may be bored from the end of the bushing and its transverse section through the wall thereof, its outer end being closed by the shown in Fig. 5 'so that when the rear part of the casing 3 is unscrewed from the cylinder, if the bearing member 9 should stick in the casing and turn with it, the dowel-pin, being spring pressed, will give and slide out on the bevel side of the recess 19.

The front head of the casing is provided with segmental openings 20 to receive and discharge the exhaust from the ports 21 in a plate 22 seated between said head and the cylinder. Said openings 20 are of greater length than the ports 21 to allow for any variation in the position of said openings and ports when the front part of the casing is screwed in place against the abutment. Said plate 22 is secured by dowel-pin 23 to the cylinder so as to hold the exhaust ports 21 in proper relation to the cylinder.

Conduits 2 1 extending from the inlet ports 13 to the front end of the rotary motor member admit the motive agent to said end to balance said member; and a cross-port 25 from the working chamber is also to be used for this purpose. I preferably enlarge the conduit 24 at its outer end as shown, as I have found that such pockets, even without the supply conduits 24 and 25, give a larger area of the motive agent which acts as a cushion between the end of the rotary motor member and the wall of the chamber and reduces the friction. a

Any suitable means may be employed for introducing a lubricant with the motive agent into the motor and I have provided an opening 26 through the-plate 22 into an annular chamber 27 which has a conduit 28 leading through the front head and bushing to the front bearing for thepurpose of giv ing the lubricant in the motive agent free access to said bearing. The rear head of the casing is shown with a screw-threaded opening 29 to secure the supply conduit; and a plate 30 closes the rear end of the rear hearing of the motor. v

In Figs. 6, 7, 8 and 9 I have shown some modifications as to the admission of the motive agent and balancing the rotary motor member. journal bearing member 9 is made'shorter thus providing a chamber 30 intowhich the bushing 10 projects a sufficient distance to permit the port 15 to enter and pass transversely through the wall of said bushing from said chamber. As to balancing the rotary motor member by the pressure of the motive agent, this may be accomplished by providing openings 31 throughsaid member as shown in Fig. 10; or by providing a conduit 32 leading from the chamber 30 through the walls of the casing 3, the abutment 2.and plate 22 to the front end of the rotary motor member as shown in Figs. 6 to 9 inclusive. The longitudinal section of this conduit 32 can be made by boring from the inner ends of the casing and the transverse, sections by In .its modified form the motorboring through the periphery of the casing and closing the open ends by plugs 33.

l-Vhere the conduit passes through the abut ment 2 at 32 it is enlarged or elongated in cross-section as particularly shown in Fig. =7

to allow for any variation in the position of the conduit when the two parts of the casing,

are screwed against the abutment.
